The Impact of Galaxy Catalogue Completeness with GLADE+ on Dark Siren Cosmology: A Line-of-Sight Prior Analysis of GWTC-3 Events
Juan Esteban Rivera, Antonio Enea Romano, Rachel Gray +2
Cosmological parameters can be estimated from dark sirens, gravitational waves events without electromagnetic counterpart, by using inference methods which estimate statistically t…
Blinded Mock Data Challenge: Is the Spectral Siren Technique Robust for Measuring the Hubble Constant?
Christos Karathanasis, Suvodip Mukherjee, Lalit Pathak +5
The measurement of the Hubble constant from gravitational wave (GW) sources is one of the independent avenues to shed light on the Hubble tension, which is associated with about an…
Non parametric constraints of gravitational-electromagnetic luminosity distance ratio
Sergio Andrés Vallejo-Peña, Antonio Enea Romano, Jonathan Gair
The ratio between the gravitational waves (GW) and electromagnetic waves (EMW) luminosity distance ratio is a key observable that allows to test the nature of gravity, using gravit…
Blinded Mock Data Challenge for Gravitational-Wave Cosmology-I: Assessing the Robustness of Methods Using Binary Black Holes Mass Spectrum
Aman Agarwal, Ulyana Dupletsa, Konstantin Leyde +18
Gravitational Wave (GW) sources are standard sirens that provide an independent way to map the cosmic expansion history by combining with an independent redshift measurement either…
Gravitoelectromagnetic quadrirefringence
Antonio Enea Romano, Sergio A. Vallejo-Peña
We develop an effective approach for the study of the interaction of gravitational waves (GWs) and electromagnetic waves (EMWs), showing that quadrirefringence can be produced, a p…
The Hitchhiker's guide to the galaxy catalog approach for gravitational wave cosmology
Jonathan R. Gair, Archisman Ghosh, Rachel Gray +28
We outline the ``dark siren'' galaxy catalog method for cosmological inference using gravitational wave (GW) standard sirens, clarifying some common misconceptions in the implement…
The MESS of the CMB
Manuel Alejandro Jaramillo Rodrguez, Antonio Enea Romano, Sergio Andres Vallejo-Pena
We analyze cosmic microwave background (CMB) data taking into account the effects of a momentum dependent effective sound speed (MESS). This approach allows to study the effects of…
Model-independent approach to effective sound speed in multi-field inflation
Antonio Enea Romano, Sergio Andrés Vallejo-Peña, Krzysztof Turzyński
For any physical system satisfying the Einstein's equations, the comoving curvature perturbations satisfy an equation involving the momentum-dependent effective sound speed, valid…
Effects of the modification of gravity on the production of primordial black holes
Sergio Andres Vallejo-Pena, Antonio Enea Romano
The enhancement of the spectrum of primordial comoving curvature perturbation can induce the production of primordial black holes (PBH) which could account for part of present…
Coordinate independent approach to the calculation of the effects of local structure on the luminosity distance
Sergio Andrés Vallejo-Peña, Antonio Enea Romano
Local structure can have important effects on luminosity distance observations, which could for example affect the local estimation of the Hubble constant based on low red-shift ty…
Are primordial black holes produced by entropy perturbations in single field inflationary models?
Sergio Andrés Vallejo-Peña, Antonio Enea Romano
We show that in single field inflationary models the super-horizon evolution of curvature perturbations on comoving slices , which can cause the production of primordi…
The effects of anisotropy and non-adiabaticity on the evolution of comoving curvature perturbation
Atsushi Naruko, Antonio Enea Romano, Misao Sasaki +1
We derive the equation for the evolution of the curvature perturbation on the comoving time slice, , in the presence of anisotropic and non-adiabatic terms in the en…
